I've heard of some Saleen supercharger owners going through belts due to a flange of steel that needs to be filed down. The flange rubs the inside of the belt until it finally gives. If my memory serves me correct, I think the defect/flange is below and to the right of the supercharger pulley......around where the valve cover meets the head.
It's not a defect, it's a piece of the valve cover that is used to hold a wiring harness. I'm pretty sure the paxton/vortech instructions say to grind it off, not sure if saleen's do or not. It shouldn't affect the whipple though.

Be sure they removed the stop on the stock tensioner. I'm not sure how it would effect the belt.

well after it snapped after the first week they installed a larger idler pully off of the h.o. kit whipple said it was better for the belt...but like i sais.. it squealed like crazy and i drove it three weeks like that cuz they said the squealing would stop but it didnt..... this was the longest i drove without snapping a belt....so i dont think it is an alignment issue but i could be wrong and i didnt get any picks of the belt, cj's took pics of it and sent them to whipple both times and both belts were directly from whipple they are made by DAYCO speacially for these kits, or thats what whipple told cj's

now if they didnt grind this tensioner stop off, why did the car run fine with the bigger idle pully? when it was on i checked the belt after every drive and it showed no sign of wear or tear
I don't know, i'm just looking for things they might have missed that would affect the belt.

when yo snap the belts are you driving straight. i do ask that for a reason. also if the set up was squeking with the after market idler, chances are its was not aliigned. one last thing. r u using the correct size belt. you might want to try a little biiger size belf.
as for the grididng of the pulley tensioner. they recommend that becasuse twin screw blowers use a cerpentine belt obviously. when you turn really hard, like tying to fish tail etc etc, the power stering pup and all that stuff will put so much strain on the belt, it will snap it. if you ging the stopper down then the tensioner can move further to give the belt slack and prevent the belt from snapping. i heard many people having this issue with whipples. if all else fails i say try a little bit bigger if a belt
yes i am driving straight both snaps were on a 3rd to 4th gear shift. and yes both belts were the correct belts it is a special belt made special for the whipple kit. and as of today my car has been broke for 2 weeks and it still is not fixed and i dont know when it will be fixed... i was supposed to get a call back from cj's friday night or saturday but...... no one called me back... suprise suprise....
do you know the belt size. that would be helpful. get that please. do you have the belts or did you get a good look at them. were they shiny looking or did they have a grove showing any signs of ripping or did they just break
the numbers on the belt were 1247KG 20-9770 they both were the same belt made by DAYCO no i dont have either of the belts they were sent to whipple the first belt was shiny and was very sticky after a hard drive which i knew was bad, but the second belt was not shiny and didnt show any signs of wear up to the point it snapped
Loosen up the bolts that hold the blower/intake down and move it forward as much as possible. That'll cure the alignment issue. The other thing to do is change one of the idlers to a different size so you can run a 123.4" belt that is available from most auto parts stores. that will make the cost of belts cheaper, and also call whipple, sounds like you need a spacer
Because of the noise you reported, I am more inclined to think you have a problem with the tensioner which is making the belt slip, and in consequence accelearating belt wear leading to failure. I assume all of the pulleys move freely and have no dents. Missalignmnet can cause belt shredding but the noise it makes is different to the one caused by slippage.
